Actors' Union condemns slap at Oscars

(Los Angeles, CA) -- The fallout is growing over the Oscars slap heard around the world.

The Screen Actors Guild is the latest to react, calling Will Smith's actions unacceptable. The actor himself admitted the same in a posted apology to Chris Rock Monday. He walked on stage and hit the comedian Sunday night over a joke about Smith's wife.

SAG-AFTRA is vowing to take action against the best actor winner and the Academy has launched a formal review.
